Software Deployment

As you say you are using a transform i assume, that you are trying to deploy a MSI.
What have you tried?
Which dialog boxes? Is it any particular or are we talking about the Installation Wizard you wish to hide?

Thank you for the response...

This is what has happened.... when trying to make a transform on the vendor supplied msi I get a error message saying ' This package does not support hidden dialogues' ... well i went ahead and made a transform anyways .... which infact does work to install the msi... Now the issue arises on making it install silently.... Even with /qb or /qn switches it does not install silently... UI intervention is prompted for the installation....

You can ignore that message box. It's not an error, it's for information purposes.

The dialogs you're seeing are almost certainly appearing as a result of Custom Action execution. Re-run the install, this time with a verbose log. Then, when you see the first dialog, open the log. Use a proper text editor that bypasses file locks: Notepad won't be able to open a log while MSIExec has a handle on it. The last line in the log - or one pretty close - should detail the Custom Action which just executed.

Once you know the CA's name, you can experiment with having it not execute, normally by applying an impossible-to-meet condition e.g. 0=1 on its execution.
